Description
Technical field
The present invention relates to wireless communication technology, particularly relate to the method and the control device of load balancing in a kind of WLAN (wireless local area network).
Background technology
Continuous development along with wireless communication technology, wireless lan (wlan) also develops rapidly as last mile (last mile) access technology of high bandwidth, the focus that the wlan device that is seen everywhere constitutes, the hot-zone, wireless campus, wireless community, the wireless city, because Radio Resource is limit, the heap(ed) capacity that each access point (AP) can provide is limited, and owing to be wireless access, customer location is unfixed, if not by certain management means, be difficult to guarantee that each AP can both give play to maximum performance, so it is exactly the technology focus that everyone pays close attention to that the load balancing technology is disposed beginning from the WLAN zone.
Load balancing also is load balancing (Load Balance), and its most basic notion is exactly that flow evenly distributes in network, and some network of reason is not because of busy and congested, and other networks are very idle.Because wireless signal can use the different frequency transmission, and tranmitting frequency also may be different, and this makes the load balancing technology complicated more in wireless network.
The business datum that inserts the user of AP at present can send to other user by dual mode, a kind of is to concentrate forwarding by access controller (AC), in this case, AP and AC can set up a data tunnel, and all user service datas can be sent to AC and go up forwarding.Another kind is that AP only sets up control channel with AC, does not set up data channel, and user service data is directly transmitted by AP, and in this case, AC only is responsible for the configuration management of AP.
The load balancing of wireless access is in order more reasonably to distribute bandwidth; usually can in AC, store tabulation and the situation of whole distribution AP; AC is according to certain algorithm; indicate some to connect the more AP of number of users wireless user in its coverage or terminal are disperseed to be connected on the contiguous AP, thereby realize load balancing.Main load balancing technology is for each user's thresholding of AP regulation or total flow thresholding at present, and after finding that access customer number or total flow arrive this thresholding, the user that new application inserts will preferentially be linked into other AP, thereby realize load balancing.Referring to Fig. 1, Fig. 1 is the schematic diagram of prior art load sharing method, STA1, STA2, STA3 have been linked into AP1, at this moment, AP1 has reached load-threshold, when the STA4 application inserts, because AP1 has reached load-threshold, and AP2 does not reach load-threshold as yet, so STA4 preferentially is linked into AP2.
Present load balancing technology, only insert at new application and also have that other AP can insert situation under just can come into force, and in actual applications, be not can both reach this requirement at every turn.Referring to Fig. 2, Fig. 2 is the schematic diagram of the shortcoming of prior art load sharing method, STA1, STA2, STA3 have been linked into AP1, at this moment, AP1 has reached load-threshold, when the STA4 application inserts, method according to the prior art load balancing, STA4 can preferentially select other AP, as AP2, yet, because STA4 is not in the access scope of AP2, therefore, STA4 can only be linked into AP1, because the Ap1 load has surpassed load-threshold, thereby the flow that causes inserting the user of AP1 is restricted, simultaneously, because AP2 does not also reach thresholding, therefore caused the wasting of resources.
In sum, existing load sharing method is accurate not enough, can not make network performance reach best.

Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer,, the present invention is described in further detail below in conjunction with the accompanying drawing embodiment that develops simultaneously.
Main thought of the present invention is: AP uses smart antenna, utilize smart antenna to obtain positional information between AP, when having the user to insert current AP, if current AP has reached load-threshold and when not having other AP can insert this user, according to location information notification neighbor AP between AP antenna beam is switched to the direction of current AP, make neighbor AP might insert this user, thereby reach the purpose of load balancing, make network performance better.
Technical scheme of the present invention can be realized by access controller (AC), also can realize that to be embodied as example by AC, the present invention will be described below with the server that AP carry out information interaction by one.Referring to Fig. 3, Fig. 3 is the schematic flow sheet of the method for load balancing in the embodiment of the invention WLAN (wireless local area network), and idiographic flow may further comprise the steps:
Smart antenna is an aerial array, is made up of N antenna element.Link to each other with radio frequency by choosing different antenna elements, can form antenna beam, thereby make AP produce different coverage diagrams with different directions characteristic.
When network just starts, the AP poll switches intelligent antenna beam, and record AP receives the signal strength signal intensity of other AP when using each antenna beam, receive the signal strength signal intensity of other AP during according to different antennae wave beam that uses and use different antennae wave beam, determine positional information between AP, comprise the neighbor AP of AP and the position relation of neighbor AP and AP.In fact, no matter use which kind of antenna beam, as long as can receive other AP, for example the signal of APx just illustrates that APx is the neighbor AP of oneself; If AP receives the signal of APx in certain antenna beam the strongest, APx then is described in one group of antenna footprint of this antenna beam representative of AP, also just determined the position relation of APx and AP thus.
Because AP fixes usually, so positional information is also fixed usually between AP, therefore, AP poll switching intelligent antenna beam obtains between AP positional information and only need carry out when network startup.
AP positional information between AC transmission AP can be carried out when AP inserts AC, also can send the request of obtaining positional information between AP to AP by AC, after AP receives this request, sends positional information between AP to AC.
In this step, to be administrative staff set in advance according to the actual needs of each AP the load-threshold of AP, and the load-threshold of AP can be a number of users, also can be total flow, or the combination of number of users and total flow.
Here, the load-threshold of AP also can be to be set in advance on AP by administrative staff, and the load-threshold with AP when AP inserts AC sends to AC.
After the user sends the request of seeking (Probe Request), if certain AP receives the described request of seeking, illustrate that then this user can insert this AP, in this step, all AP that can receive the request of seeking of user's transmission can notify AC.
In this step, the AC record sends all AP of this notice, and generation can insert this user's AP tabulation.
When step 306, new user need insert current AP, new user sent to current AP and inserts message, and current AP receives and sends this accesss message after new user's the access message and arrive AC.
In this step, AC judges according to load-threshold and the present load of current AP whether current AP has reached load-threshold.
In this step, because therefore current AP no show load-threshold still allows new user to insert current AP, cut-in method is same as the prior art, repeats no more.After new user inserted current AP, the load of current AP increased, and therefore also will revise the present load of AP.
In this step, the AP tabulation that AC can insert according to the new user of record, judgement can insert in this new user's the AP tabulation whether the AP that does not reach load-threshold is arranged, if having, then new user has other AP to insert, otherwise new user does not have other AP to insert.
Because the positional information between AP determines that therefore, AC only need get final product to the direction switching of current AP according to the neighbor AP of the current AP of location information notification between AP.
Behind the neighbor AP switched antenna wave beam, its coverage changes, new user might be in the coverage of the neighbor AP after the switching, after new user sends the request of seeking, AC just can be known all AP that can insert this new user, therefore, behind neighbor AP switched antenna wave beam, the AP tabulation that the user who obtains once more according to AC can insert, judgement can insert in this user's the AP tabulation whether the AP that does not reach load-threshold is arranged, if having, then new user can insert other AP, otherwise new user does not have other AP to insert.
In this step, in the AP tabulation that can insert this new user the AP that does not reach load-threshold is arranged, AC selects an AP to insert this new user from the AP that does not reach load-threshold that can insert this new user at random, and revises the present load of this selecteed AP.
In this step, all neighbor AP of current AP are behind the switched antenna wave beam, still can not cover this new user's in-scope, can not insert under this new user's the situation, this new user can only insert current AP, but, this moment, current AP reached load-threshold, therefore, for load balancing, after current AP inserts this new user, poll switched antenna wave beam, and record receives the intensity of this new user's signal when using each antenna beam, but with antenna beam to this new user side of deflection to and the direction that departs from the roamer switch, but also promptly switch to receiving the strongest and direction that depart from the roamer of this new subscriber signal.When but the antenna wave beam departs from the roamer, but the roamer can disconnect and being connected of current AP, but roaming is linked into other AP that can insert this roamer, but when the roamer disconnect with being connected of AP after, the present load of current AP reduces, thereby has reached the purpose of load balancing.But the roamer here is meant the user who has two and plural AP to insert who inserts current AP.But the roamer disconnect with being connected of current AP after further comprise: the load-threshold of revising current AP.
Be that example is illustrated the present invention with Fig. 4,5 below.Referring to Fig. 4, Fig. 4 is the schematic diagram that embodiment of the invention original user inserts AP, wherein there are AP1, AP2, three AP of AP3 that certain zone is covered, five users of STA1-STA5 for having inserted, wherein STA1-STA3 is linked into AP1, STA4 is linked into AP2, STA5 is linked into AP3, and for the load-threshold of load balancing setting is 3 users, the flow of supposing each user is 10Mbps, the total flow upper limit of each AP is 30Mbps, and STA6, STA7, STA8 are three users that successively reach the standard grade.
According to load sharing method of the present invention, the situation after STA6-STA8 inserts as shown in Figure 5, Fig. 5 uses the schematic diagram that the embodiment of the invention inserts new user.When STA6 inserted, because AP1 has arrived load-threshold, STA6 inserted AP2; When STA7 inserted, STA7 can only insert AP1, and the antenna beam of AP2, AP3 is switched to the AP1 direction, found the AP3 after STA7 can insert the switched antenna wave beam; When STA8 inserts, the antenna beam of AP2, AP3 after AP1 switches, still can not be linked into AP2 or AP3, then STA8 is inserted AP1, antenna beam with AP1 switches to the direction of STA8 simultaneously, but departs from roamer STA2, makes the STA2 roaming be linked into AP2.As seen from Figure 6, use the present invention, the user is evenly distributed in the network, and AP1-AP3 does not exceed load-threshold.
The present invention also provides the control device of load balancing in a kind of WLAN (wireless local area network), this device can be arranged among the AC or one can carry out in the server of information interaction with AP.
Referring to Fig. 6, Fig. 6 is the schematic diagram of the control device of load balancing in the WLAN (wireless local area network) of the present invention, the WLAN (wireless local area network) that this device is applied to use the AP of smart antenna to set up mainly comprises information acquisition module 701, information storage module 702, load balancing module 703, wherein:
Here, positional information is to be determined and sent to information acquisition module 701 by AP poll antenna beam and signal strength signal intensity of receiving other AP according to the different antennae wave beam that uses and when using the different antennae wave beam when network just starts between AP.Information acquisition module 701 receives between the AP that AP sends after the positional information and positional information between the AP that obtains to be sent to information storage module storage 702.
The AP tabulation that the user that information storage module 702 is further used for receiving and stored information acquisition module 701 is sent can insert;
Load balancing module 703 in the neighbor AP of notifying current AP before the direction switched antenna wave beam of current AP, load-threshold and present load according to the current AP of storage in the information storage module 702 judge whether current AP reaches load-threshold, if current AP does not reach load-threshold, then there is the AP that does not reach load-threshold can insert this user, notify current AP to insert this user, and the present load of the current AP that stores in the modification information storage module 702, otherwise, if in the AP that the user of storage can insert in the information storage module 702 tabulation AP that does not reach load-threshold is arranged, then there is the AP that does not reach load-threshold can insert this user, in the described AP that does not reach load-threshold, select an AP to insert this user, and revise the present load of this selecteed AP of storage in the information storage module 702; Notifying neighbor AP behind the direction switched antenna wave beam of current AP, judge according to the load-threshold of AP of storage in the information storage module 702 and present load whether AP that the user can insert has the AP that does not reach load-threshold in tabulating, if have, then in the described AP that does not reach load-threshold, select an AP to insert this user, and revise the present load of this selecteed AP of storage in the information storage module 702.
